Abstract

Gastric mucosal blood flow in the rat was determined by the indicator fractionation technique 86RbCl. Antral and corpus flow rates were determined after increasing periods of fasting, and the effect of vagotomy was assessed. The physiological stimulus of food in the stomach markedly increased antral as well as corpus blood flow, and after vagotomy lower flow rates were recorded in all parts of the stomach. With progressive starvation, the antral:corpus flow ratio decreased. The findings suggest that the antrum plays an active role in response to a physiological stimulus and may, as has been suggested by others, contribute to the control of parietal cell blood flow and secretion.

摘要

采用放射性示踪剂分馏技术86RbCl测定大鼠胃黏膜血流量。在禁食时间延长后测定胃窦和胃体的血流速率，并评估迷走神经切断术的效果。胃内食物的生理刺激显著增加了胃窦和胃体的血流量，迷走神经切断术后胃各部位的血流速率均降低。随着饥饿程度的加重，胃窦与胃体的血流比值下降。研究结果表明，胃窦在对生理刺激的反应中发挥着积极作用，并且可能如其他人所提出的那样，有助于控制壁细胞的血流和分泌。
